    Emergency Informatics and Digital Libraries: Workshop for JCDL 2012
    Yang, Seungwon; Fox, Edward A. (2012-06-01)
    There is growing global awareness of the need for information in connection with emergencies, crises, tragedies, disasters, and related recovery activities. Yet, there is little integration of the diverse types of related information, minimal connection with the digital library community, and almost no awareness of the need for related digital library research and development. This workshop will bring together key stakeholders from the many agencies and organizations in the area, as well as researchers with interdisciplinary perspectives, to explore these opportunities with those in the DL community who are interested. This will build upon work on the NSF-funded Crisis, Tragedy, and Recovery Network (www.ctrnet.net) DL project, and its collaboration with the Internet Archive, to identify, capture, preserve, and make accessible information about worldwide natural and manmade disasters as they occur. The CTRnet team will help with accomplishing the objectives listed below, ensuring a permanent record of findings and information shared during or after the meeting.

    Twitter Use During an Emergency Event: The Case of UT Austin Shooting
    Li, Lin Tzy; Yang, Seungwon; Kavanaugh, Andrea L.; Fox, Edward A.; Sheetz, Steven D.; Shoemaker, Donald J. (2011-06-01)
    This poster presents one of our efforts developed in the context of Crisis, Tragedy, and Recovery Network (CTRnet) project. One of our derived works from this project is the use of social media by government to respond to emergency events in towns and counties. Monitoring social media information for unusual behavior can help identify these events once we can characterize their patterns. As an example, we analyzed the campus shooting occurred in the University of Texas, Austin, on September 28, 2010. In order to study the pattern of communication and the information communicated using social media on that day, we collected publicly available data from Twitter. Collected tweets were analyzed and visualized using Natural Language Toolkit, word clouds, and graphs. They showed how news and posts related to this event swamped the discussions of other issues.
